Patient care communication system

ABSTRACT

A patient care facility communication system with a plurality of communication terminals operatively coupled together for the transmission and receipt of messages, includes a program providing a message composition facility by which an operator may select one or more common items from a plurality of data screens, such as patient lists, address lists, work-item lists, and common message lists, to be included in messages frequently required to be sent for the efficient operation of the patient care facility.

This application is a division of copending application Ser. No. 06/771,320, filed on Aug. 30, 1985, U.S. Pat. No. 5,101,476.

BACKGROUND OF THE INVENTION

This invention relates generally to communication systems and more particularly to a patient care system for use in hospitals and other patient care environments to provide a means for a highly efficient multiple-message and information communication facility

As recent discoveries and developments in electronics and the physical sciences are applied to the medical profession, significant inroads are being made with regard to the diagnosis and treatment of a wide variety of human afflictions. Today it is possible to accurately measure many more variables which may be related to a patient's illness and to correlate those variables quickly and easily into a new meaningful patient diagnosis and/or statement of condition. Moreover, technological developments are being applied to all aspects of the hospital environment including radiology, laboratories, intensive care units, cardiology, nuclear medicine and even dietary units and prescription supplies. These advancements in the state of the art not only provide better and faster care for patients but also provide such improved care using fewer personnel.

The increased availability of patient-related data and information has created a need for improved communication systems throughout the many departments and laboratories in a hospital environment especially since much of the data is interrelated and data input from one source should be made known and coordinated with many other departments in a timely and efficient manner.

Many hospitals today have computerized communications systems in order to rapidly and accurately disseminate patient-related data to various communications stations throughout the patient care facility. Such systems include a main facility computer with communication terminals located throughout the facility at strategic locations. For example, there may be two or three nursing stations on each floor of a hospital with each station having a communication terminal and being responsible for the care and treatment of a predetermined number of patients in the immediate area. Additionally, each specified area, such as radiology, pharmacy, laboratory and nutrition, may have a separate terminal by which communications and test results may be sent to and/or received from any other specialized area or nursing station terminal.

Notwithstanding the relative sophistication of these communication systems, their efficiency has been limited since inputs are required from operating personnel and to the extent that the systems are complicated to format and/or operate (i.e. not "user friendly"), extensive specialized training or the hiring of specialist personnel may be required. Moreover, many such systems are "serially oriented" and can transmit or receive information or data related to only one patient at a time or to only one terminal at a time or with regard to only one treatment activity or "work-to-be-done" item. For example, in a typical communication system, the operator may type the entire message and perhaps for each destination. The message may contain patient names and locations, doctors' orders, and text. Such an arrangement requires an operator to repetitively input much of the same data with regard to each individual patient, destination, and/or treatment activity. Therefore, to the extent that these communication systems are serially oriented, duplicative of operator inputs are required and the full efficiency potential of the system is not being realized. In addition, with an improved communication system, highly-skilled patient care personnel would be able to devote more of their time to the care of patients and less time operating a communication terminal.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide an improved patient care communication system which is menu driven for maximum user friendliness and which couples a general message transmission facility with a multiple selection of destinations, patients, work-to-be-done, and/or common message text displays or menus to substantially reduce the need for repetitive typing of the same input data in a patient care program utilized by hospitals and other patient care facilities. A message concerning one or a plurality of patients selected from a screen census can be transmitted selectively to a number of different departments or units within the hospital concerning work to be performed with respect to those patients Similarly, a work-list-oriented message including worklist items selected from a menu can be sent to selected units with respect to particular patients.

DETAILED DESCRIPTION OF THE INVENTION

The present invention, as disclosed herein, is shown in a patient care operating environment, although the invention may be applied in various other fields of activity to effect more efficient and less time consuming communications among groups of users of computer-related communications and data processing equipment.

In the present example, a typical patient care facility includes many different functional areas such as a plurality of nursing units each with the responsibility for a number of patients, various laboratories and analysis areas such as blood analysis, and x-ray, together with specialized areas such as intensive care and coronary care. The present invention may be implemented in a system which includes a communications station at each of these locations. Typically, such a communications station would include a keyboard for entering data along with a display screen and a printer. The terminals may be so called "intelligent terminals" tied together by a network with a central computer for information processing or so called "dumb terminals" which totally rely on and are connected together by means of a central computer system.

In accordance with the present invention, the computer system is programmed in accordance with the flow charts illustrated in the attached figures to accomplish the communication of a common message referencing a plurality of patients to a number of predetermined addressees or to send worklist related messages to various units also referencing a plurality of patients in such units.

For example, it will be assumed that one of the nursing stations in the hospital has several patients who have been detained at the x-ray unit and are not available for the scheduled lunch. This could be a relatively common occurrence in many hospitals and in many cases a nurse would have to phone the dietary unit, wait to get a connection to the appropriate person, and advise that person of the situation. Alternatively, in some hospital systems this could be done electronically, but the user of the terminal for that particular nursing station would have to send individual messages with regard to each patient which would entail repetitive keying in of the same information for the several patients who are not available.

In the exemplary embodiment of the present invention, the terminal operator is assumed to already be "on-line", i.e., the user has already logged onto the system and entered a password which is automatically checked before the user is authorized to continue processing information on his particular terminal. That procedure is indicated in block 1 "SIGN ON" and block 3 "CHECK AUTHORIZATION" in FIG. 1. If the user does not have the proper sign-on procedure or does not have a valid password, the terminal is returned to the SIGN ON screen or may be directed to a HELP screen or other procedure required to effect proper initialization of the system terminal.

If the operator is authorized, the program proceeds past decision block 5 to display the user's MASTER SCREEN at block 7. The MASTER SCREEN generally displays a list of functions or operations available to the user which may be implemented by selecting the desired function. That selection process may be accomplished by means of keying in a number identified with the function on the screen or keying a program function ("PF") key, or by indicating the selected functions by using a light pen or any other input means generally known and available for such systems. Note: In the sample screens which follow, selection may be accomplished by a light pen or by typing. The "!" does not appear on the screen but is shown to indicate an immediate computer response when the light pen is used. The "?" is used to indicate a delayed computer response and is used when more than one selection is desired on the screen. If typing a selection, the operator would type an "X" in the field delimited by a "<" and ">". Typically those delimiters are not displayed on the screen.

A typical nursing UNIT SUPERVISOR MASTER screen is shown below:

    ______________________________________                                         UNIT SUPERVISOR MASTER   <11/21/84 09:17>                                      ______________________________________                                         Select one of the following:                                                   !03 Change Unit Patient Profiles                                               !17 Display Patient Profiles (Unit)                                            !21 Display Unit Worklist                                                      !39 Enter Results (Chart) for Unit                                             !41 Identify Patient for Processing                                            !55 Process Unverified Orders (Unit)                                           !71 Send Message                                                               !72 Send Patient-Oriented Message                                              Selection ==><72>                                                              SIGNOFF=S:< >:                                                                 <GENERAL HOSPITAL>    OPERATOR, SALLY>                                         ______________________________________                                    

One of the functions on the MASTER screen is identified as "Send Patient-Oriented Message" (POM). If the Patient-Oriented Message function is not selected, the program will check the input to determine which function was selected on the master screen as indicated by the decision block 9. If the POM function has been selected, the program next displays the DESTINATION screen as indicated by block 11.

The DESTINATION screen as shown below is also menu-driven and designed to have the user identify the DESTINATIONS to which the message is to be sent.

    __________________________________________________________________________     <SEND P.O.

If you wish to send a                 message to selected destinations in each group, select `Selected`              for that group. If you wish to transmit this message to all groups,            select `All Destinations`.                                                          .sub.---- Group.sub.----                                                       Nursing Units < >?

As hereinbefore noted, in general there are different types of possible destinations including one or more of the nursing units throughout the hospital, one or more of the various departments and/or other areas which cannot be categorized in either of the above two groups. The destination screen in the present example specifies an "All Destinations" input which, if selected by the user, will save all of the possible destinations in the destination file as addressees for the message to be sent as represented by blocks 13 and 15. On the "DESTINATIONS" screen, in addition to the "All" selection, the individual groups are identified as "Nursing Units", "Departments", and "other areas", and beside each group the user may select either an "All" or "Selected" input. For example, the user may select that the message should go only to Dietary Unit and, therefore, would check the "Selected" block on the menu. That choice is indicated at decision block 17 in FIG. 1. If the user wishes the message to go only to a selected department, the user would identify only the "Selected" block corresponding to the "Departments" group. At that point the program would display the individual department units comprising that group as shown in block 19. It should be noted that the list of destinations may be displayed from an existing file of destinations or an individually coded screen format. The department group units may include the various departments in the hospital which perform a service such as testing and analysis required in the care of patients such as laboratory, pharmacy, radiology, nuclear medicine, dietary, physical therapy, respiratory therapy, cytopathology, and various others depending upon the particular hospital environment. A typical DEPARTMENT DESTINATIONS screen is shown below:

In the present example, the user may indicate only the Dietary department on the menu and the program would save only the dietary location as the addressee for the message to be sent. After saving the selected addressees as indicated in block 21, the program would determine if any other groups were identified at decision block 23. If other groups were selected, the program would return to display the individual units in the other groups for selection and save those addressees as appropriate. If no additional groups were selected, the program returns to the mainstream flow which is continued at the top of FIG. 2. At that point, the program displays a PATIENT CENSUS for the user to identify one or more patients to which the message relates. An exemplary LOCATION CENSUS screen is shown below:

The Patient Census file is maintained when patients check into or out of the patient care facility and may be accessed by the terminals throughout the facility as needed. In addition, when the patient is assigned a room and bed number, that data is also stored and accessible. For example, when the Patient Census screen is displayed at block 25, the user may identify, by key input or light pen input or otherwise, the patients to which the message applies. A loop is set up in the program to Collect and Save the identities of the selected patients together with room and bed numbers as appropriate, as indicated by block 27 and decision block 29. After all of the patient selections have been collected and saved in the program, a common message screen is displayed as shown in block 31 in FIG. 2.

The COMMON MESSAGE screen as shown below, is designed to display a plurality of frequently occurring messages which are routinely sent and received during the normal operation of the patient care facility. It should be noted that the list of common messages may be displayed from an existing file of common messages or from an individually coded screen format.

This screen is designed in accordance with the particular requirements of the patient care facility but may include common messages such as "DELAY BREAKFAST", "DELAY LUNCH", "DELAY DINNER", "PROVIDE TRANSPORTATION". In addition, the COMMON MESSAGE screen includes many common responses that are required to be sent in order to confirm that messages from other units have been received and have been acted upon. For example, the COMMON MESSAGE screen includes common response and/or confirmation messages such as "PATIENTS PREPARED", "SPECIMENS COLLECTED", etc.

It should also be noted that in the present program, each screen contains a function selection by which the user may exit at any time to return to the master menu in the event that there is no longer a need to send the message being prepared.

Returning to the present example, the user would check the selection specified as "DELAY LUNCH" in order to advise the dietary department to delay lunch for the identified patients. Once the patients have returned from the x-ray facility and are ready for lunch, the terminal operator can quickly and easily send an electronic message to "RESUME LUNCH" to that dietary department so that all of the patients returning to the nursing unit may enjoy a delicious and freshly prepared lunch at their convenience.

Also in accordance with the present invention, another example would allow the nursing unit to request that the transportation department take one or more specific patients to a specific department. This invention makes it very easy to compose these types of requests and provide hard-copy for the receiving destination.

Still another use is for a nursing unit to use the invention to create a type of worklist by sending itself a message such as: typing BATHE THE FOLLOWING PATIENTS after selecting patients from the census display.

After the user has selected the particular common messages which may be applicable, the program Collects and Saves those messages as indicated in block 33 and then Displays those Common Messages at block 35 in a format which allows the user to input unique data or specific messages if required. If such specific messages are keyed in, the program Collects and Saves the total message at 37 and then determines the name of the Sender of the message at 39. In the present example, the sender's identity is gleaned from the user file in the system unless the operator wishes to input another identification such as, for example, when one user is at a terminal in another department or unit.

At this point, the program Collects and Assembles the selected patient data, Addressees and Total Message to Display to the user as shown in 41. By keying a designated Transmit or Send key, the user can transmit the message as shown in decision block 43 at which time the message in total is transmitted to the selected addressees and automatically printed at those locations for proper handling as shown in block 45. If the message is not to be transmitted, the operator may make another selection by which the entire message may be cancelled and the user returned to the Main Menu screen. A typical PATIENT-ORIENTED MESSAGE screen, which would include selected Addressees and referenced patients, together with selected common messages and keyed messages, is shown below:

Another example of the multi item message facility herein disclosed is illustrated with reference to FIGS. 3 and 4 with respect to facilities required of departments in the patient care facility. Many such departments have a need to send what are known as "worklist-oriented messagss" which relate more to services which must be performed by the departments in response to work orders placed by nurses or physicians in the facility. For example, departments need to know what has to be accomplished in the next several hours or within a certain period of time in order to assign those work items to personnel to insure the timely performance of the service. In some cases, the attending physician may require a blood sample analysis within one hour or immediately in emergency situations. In other cases where there is no immediate need, such analysis may be routinely accomplished in the normal time frame. In many cases the time requirement for sample analysis is critical and must be made known to the proper personnel and also the results of such analysis must be communicated to the appropriate station or terminal as soon as possible after they are known in order to determine or complete the most effective treatment program for the patient. Since the requirements for a department may differ from those of a nursing unit, normally the MASTER SCREEN for the department includes functions not found on the MASTER SCREEN for the nursing unit. One of the functions on the department MASTER MENU is designated "Send Worklist-Oriented Message" (WLO).

The processing associated with the selection of that function is illustrated in FIG. 3 and continued in FIG. 4. In general, the "Sign On" process and DISPLAY OPERATOR MASTER SCREEN routines 51-57 are similar to those heretofore explained in connection with FIG. 1. When the operator within a department or laboratory selects the WLO function from the MASTER SCREEN at decision block 59, a DESTINATIONS screen 51 is presented and the routine for identifying and saving the Addressees of the message to be created, as shown in block 63-73 of FIG. 3, correspond to those heretofore explained in connection with blocks 13-23 of FIG. 1.

After the Addressees have been determined and saved, the program displays a screen entitled "TYPES OF WORKLISTS" as shown in block 75 of FIG. 4. The "Types of Worklist" items which are displayed on the WORKLIST screen include time-related items such as "Next Hour", "Next Four Hours", "Next Eight Hours", "Today 7-3", "Today 3-11", "Today 11-7", "Tomorrow", etc. Other items available for selection on the menu include "Uncompleted Orders", "Unverified Results", "Verified Results", etc. A typical WORKLIST TYPE screen for a clinical laboratory is shown below:

Once the types of worklists have been displayed and one has been selected, the particular worklist for the selected type is displayed as indicated at block 77. When physician orders are placed upon departments relative to the particular patients referenced, then that information is saved in a file which is recalled in connection with the display of the worklist for a selected type of worklist. Accordingly, the DEPARTMENT WORKLIST display for the particular type of worklist includes information such as the referenced patient and the particular item ordered, with each item representing a separate service required of a single patient. If more than one service is required of a patient, then there will be a corresponding number of items in the displayed worklist. A typical DEPARTMENT WORKLIST screen is shown below:

All of the work items ordered by physicians with regard to particular patients are entered as separate items in the worklist. For example, the items designated "Within the Next Hour" were selected with the worklist "type". There may appear several requirements listed as separate items with regard to an individual patient. Patient Hahn, for example, may require both a blood analysis and an x-ray within the next hour and both of those items would be individually listed on clinical laboratory and radiology worklists, respectively. If the message were originating from the blood analysis lab, for example, the terminal user would select or identify the item designated as the blood analysis (CBC) for patient Hahn, since that is the only worklist item to which his message relates. After that selection the program Collects and Saves the selected Worklist-Patient Items at block 79 and determines whether additional items have been selected at 81. A loop is included to process any additional items and when the list is complete and no additional items have been selected and unprocessed, the program Displays a MESSAGE INPUT SCREEN at block 83. The MESSAGE INPUT SCREEN allows the operator to key in particular messages related to the particular Worklist Item and patient selected. That input message is Collected and Saved as indicated in block 85 together with the addressees previously selected by the operator. The program then Collects and Assembles the selected Worklist-Patient Items together with the particular message keyed in at block 87 and displays a WORKLIST-ORIENTED MESSAGE screen as shown below.
